Metroid Prime 3: Corruption > Metroid Prime: Hunters > Metroid Prime 1 and 2: Echoes > Super Metroid > Metroid Zero Mission = Metroid Fusion > Metroid II > Metroid > Metroid Pinball.
I've played and beaten all of them, minus Metroid Pinball.
Seriously, we need MP stuff. While this stage is nice, the next Metroid stage needs to be Prime-based. Super Metroid is long gone. I haven't seen a ALTTP stage in SSB, and that game is far to superior to Super Metroid. And it's only two or three years older. 1 Super Metroid stages is enough. Give the next 1-3 to Prime, seriously. Maybe 1 to Fusion, or Zero Mission! SERIOUSLY! Pretty much all the Super Metroid SSB stages failed (minus Brinstar in SSB64, and that barely was good, while Brinstar Melee amd Brinstar Depths sucked worse then Mewtwo on the tiers). Point is this looks like the first EXTREMELY GOOD Metroid stage, and since all of them have been based on Super Metroid...that needs to chage, seriously. Brinstar Depths should die. DIE! DIE!
And that sucks taht Samus doesn't have the Light Suit, Fusion Suit, Dark Suit, Phazon Suit, SR Phazon suit thingy from Metroid Prime 3: Corruption, or any other suits as alternate outfits. Well, we haven't seen any yet, though I got a good feeling about the Light Suit, and maybe the Dark (not Dark Samus) suit. Simply put, Metroid Prime 3: Corruption is a instant legendary classic game, and deserves to be repped in Brawl. END OF DISCUSSION!
